Tableau ─ Data Types
Data Type Description Example
STRING Any sequence of zero or more characters. They are
enclosed within single quotes.
'Hello'
'Quoted'
'quote'
NUMBER These are either integers or floating points. 142.58
BOOLEAN They are logical values. TRUE
FALSE
DATE &
DATETIME
Tableau recognizes dates in almost all formats. "02/01/2015"
"#3 March
1982"

Calculations (Operators)
Types of Operator
• General Operators
• Arithmetic Operators
• Relational Operators
• Logical Operators

General Operators
Operator Description Example
+(addition) Adds two numbers.
Concatenates two strings.
Adds days to dates.
7 + 3
Profit + Sales
'abc' + 'def' = 'abcdef'
#April 15, 2004# + 15 = #April 30,
2004#
–
(subtraction)
Subtracts two numbers.
Subtracts days from dates.
-(7+3) = -10
#April 16, 2004# - 15 = #April 1,2004#

Arithmetic Operators
*(Multiplication) Numeric multiplication 23*2 = 46
/(Division) Numeric division 45/2 = 22.5
%(modulo) Reminder of numeric
division
13 % 2 = 1
^(power) Raised to the power 2^3 = 8

Comparison Operators
= = or =
(Equal to)
Compares two numbers or
two strings
‘Hello’ =
‘Hello’5 = 15/ 3
!= or <> (Not
equal to)
Compares two numbers or
two strings or two dates to
be unequal.
‘Good’ <>
‘Bad’
18 != 37 / 2
> (Greater than) Compares two numbers or
two strings or two dates
[Profit] > 20000
[Category] > ‘Q’
[Ship date] > #April 1,
2004#
< (Less than) Compares two numbers or
two strings or two dates
[Profit] < 20000
[Category] < ‘Q’
[Ship date] < #April 1,
2004#

Logical Operators
AND If the expressions or
Boolean values present on
both
[Ship Date] > #April
1, 2012# AND
[Profit] > 10000
OR If any one or both of the
expressions or Boolean
values present
[Ship Date] > #April
1, 2012# OR
[Profit] > 10000
NOT This operator negates the
Boolean value of the
expression present after it.
NOT [Ship Date] >
#April 1, 2012#

Tableau ─ Functions
• Following are the description of different ca
tegories of functions.
• Number Functions
• String Functions
• Date Functions
• Logical Functions
• Aggregate Functions

Number Functions
• Function Description Example
• CEILING (number)
• Rounds a number to the nearest integer of equal or
greater value.
• CEILING(2.145) = 3
• POWER (number,power)
• Raises the number to the specified power.
• POWER(5,3) = 125
• ROUND (number,[decimals])
• Rounds the numbers to a specified number of digits.
• ROUND(3.14152,2) =3.14

Tableau ─ LOD Expressions
• Level of Detail (LOD) expressions are used to run complex queries involving many
• dimensions at the data source level instead of bringing all the data to Tableau
interface. A
• simple example is adding dimension to an already calculated aggregate value.
• Types of LOD
• There are three main types of LOD expressions.
• FIXED LOD: This expression computes values using the specified dimensions
• without reference to any other dimensions in the view.
• INCLUDE LOD: This level of detail expressions compute values using the
specified
• dimensions in addition to whatever dimensions are in the view.
• EXCLUDE LOD: These levels of detail expressions subtract dimensions from the
• view level of detail.
